摘要: 在预先镀有ZnO纳米层的(0001)蓝宝石衬底上利用低温水热法制备出ZnO薄膜。SEM和XRD显示此ZnO膜是由六棱柱状阵列构成的,基于蓝宝石衬底生长,具有高度的c轴择优取向,且(0004)摇摆曲线的FWHM达到1.8°。并发现了在水热溶液中加入一定量六次甲基四胺可以调节六棱柱状ZnO尺寸比例。 |

Abstract: Well-aligned ZnO films have been prepared by using low-temperature hydrothermal approach on (0001) sapphire substrates pre-coated with a ZnO nano-layer by dip-coating. The characterization results by scanning electron microscopy (SEM) and X-ray diffraction (XRD) indicate that the ZnO films consist of hexagonal rods growing along c axis based on sapphire substrates. The size of ZnO rods could be adjusted by an aqueous solution with methenamine. |
Keywords: ZnO arrays, hydrothermal approach, (0001) sapphire substrates |
